In order to more clearly explain the method for upgrading a system provided by the above embodiment, by combining the contents of the above embodiment and taking the following Embodiment 2 as an example, a method for upgrading a system is explained in detail in the following Embodiment 2.

Embodiment 2

The present embodiment provides a method for upgrading a system, the systems to be upgraded in the present embodiment includes two synchronized systems, and any one of the two systems is currently used, the other system not used currently is a mirror system corresponding to the currently used system. With reference to Fig.2, the flow of the method provided by the present embodiment may be shown as follows:

Step 201: determining a currently used system, and synchronizing system files of the currently used system to a corresponding mirror system;

When this step is specifically performed, the present embodiment does not limit a specific time at which the step 201 is performed. For example, in order to guarantee synchronization between the currently used system and the corresponding mirror system, a synchronizing period may be preset, by which the step 201 is periodically performed. Wherein, the present embodiment does not limit a specific length of the preset synchronizing period, for example, the synchronizing period may be preset to be a week or a day. Besides, the step 201 may also be performed while it is determined that a system upgrade is required to be performed in accordance with the method for upgrading the system provided by the present embodiment.
In addition, the system files of the currently used system include BOOT files and SYSTEM files. Thus, when the step of synchronizing the system files of the currently used system to the corresponding mirror system is implemented, it is required to synchronize the BOOT files of the currently used system to the corresponding mirror system, and to synchronize the SYSTEM files of the currently used system to the corresponding mirror system after the BOOT files are successfully synchronized. If the process to synchronize the BOOT files of the currently used system to the corresponding mirror system fails, or the process to synchronize the SYSTEM files of the currently used system to the corresponding mirror system fails, the synchronizing process between the currently used system and the corresponding mirror system is determined to be failed. In order to successfully perform subsequent processes for upgrading the system, the method provided by the present embodiment may repeatedly perform the synchronizing process between the two systems till the synchronization is succeeded, and then subsequent upgrade steps continue to be performed. Besides, a specific method for implementing the step of synchronizing the system files of the currently used system to the corresponding mirror system may also be other methods. The present embodiment does not limit a specific method for implementing the step of synchronizing the system files of the currently used system to the corresponding mirror system.
Step 202: obtaining a system upgrade package;
With respect to this step, the present embodiment does not limit a specific method of obtaining an upgrade package. The method includes downloading a corresponding system upgrade package from a network, but it is not limited thereto.
In one embodiment, in order to make the method for upgrading a system provided by the present embodiment be more conforming to a user's actual needs, before obtaining the system upgrade package, it is searched whether a corresponding system upgrade package is present in the network, and a prompt indicating that the system upgrade package is present is displayed if the corresponding system upgrade package is present, to allow a user to confirm according to the prompt whether to perform the system upgrade; and the corresponding system upgrade package is downloaded from the network after information indicating to perform the system upgrade determined by the user is obtained.
The present embodiment does not limit a specific searching time at which it is searched whether a corresponding system upgrade package is present in the network. For example, a searching period may be set, such that it is periodically searched whether the corresponding system upgrade package is present in the network. Wherein, the set searching period can be any length, for example, the searching period may be set to be an hour or a day or the like. Furthermore, the present embodiment does not limit a specific searching method for searching whether a corresponding system upgrade package is present in the network. The method includes determining a version number of the currently used system, and searching whether a system upgrade package corresponding to the version number is present in the network according to the version number of the currently used system, but it is not limited thereto. The present embodiment does not limit a specific displaying method for displaying a prompt indicating that the system upgrade package is present. The method includes popping up a prompt window indicating that the system upgrade package is present, but it is not limited thereto. The present embodiment does not limit a specific determining method for obtaining information indicating that the user determines to perform a system upgrade. The method includes using obtained information indicating that a user clicks a specified button in the prompt window, which indicates that the system upgrade package is present, as information indicating that the user determines to perform the system upgrade, but it is not limited thereto.
It is to be explained that, since the present embodiment does not limit a specific searching time at which it is searched whether a corresponding system upgrade package is present in the network, if it is searched out that the corresponding system upgrade package is present in the network before the step 201, and the confirmation information indicating that the user determines to perform the system upgrade is obtained, the step 202 of downloading the corresponding system upgrade package form the network is performed directly in the currently used system, and then the step 201 is performed, at this time, the system upgrade package included in the synchronized mirror system is the system upgrade package that is synchronized from the currently used system. If it is searched out that the corresponding system upgrade package is present in the network after the step 201, and the confirmation information indicating that the user determines to perform the system upgrade is obtained, the step 202 is performed in the synchronized mirror system to download the corresponding system upgrade package form the network after the step 201 is performed, at this time, the system upgrade package included in the synchronized mirror system is the system upgrade package that is downloaded from the network. Thus, the present embodiment does not limit a specific sequence of performing the steps 201 and 202.
Step 203: upgrading the synchronized mirror system according to the system upgrade package;
With respect to this step, the present embodiment does not limit a specific upgrading method for upgrading the synchronized mirror system according to the system upgrade package. For example, the obtained system upgrade package is analyzed, and it is determined whether the analysis is normal according to a digital signature, and if the analysis is normal, files in the system upgrade package are updated to the synchronized mirror system in manner of patches in the synchronized mirror system.
Step 204: starting the upgraded mirror system after the synchronized mirror system is successfully upgraded, and using the upgraded mirror system as the currently used system.
With respect to this step, the present embodiment does not limit a specific time at which the upgraded mirror system is started. For example, after the synchronized mirror system is successfully upgraded, the upgraded mirror system may be started when the system is restarted. For another example, after the synchronized mirror system is successfully upgraded, a starting identifier may be set and displayed to allow a user to confirm according to the starting identifier whether to start the upgraded mirror system, and an operation of starting the upgraded mirror system is performed after information indicating that the user determines to start the upgraded mirror system is obtained. A specific method for setting the starting identifier includes setting a specific parameter that represents the starting identifier, but it is not limited there to. The parameter value is used as identifier that determines whether to start or not. For example, when the parameter value is 0, it is a non-starting identifier, and when the parameter value is 1, it is a starting identifier. Certainly, the starting identifier may also use other numerical numbers to represent non-starting or starting. The present embodiment does not limit specific numerical numbers by which the starting identifier represents non-starting or starting. The present embodiment does not limit a specific method for displaying the starting identifier. The method includes displaying the starting identifier in manner of popping up a prompt window of the starting identifier to allow a user to confirm whether to start the upgraded mirror system by clicking the prompt window, or displaying a button that represents the starting identifier to make the user determines whether to start the upgraded mirror system by clicking the button, but it is not limited thereto. After information indicating that the user clicks the prompt window or the button that represents the starting identifier is obtained, the obtained information indicating that the user clicks the prompt window or the button that represents the starting identifier may be used as the obtained information indicating that the user determines to start the upgraded mirror system. The present embodiment does not limit a specific obtaining method for obtaining information indicating that the user determines to start the upgraded mirror system.
In one embodiment, in order to maintain synchronization between a currently used system and a mirror system, after the upgraded mirror system is used as the currently used system, system files of the upgraded mirror system are synchronized to the previously used system. The present embodiment does not limit a specific synchronizing method for synchronizing the system files of the upgraded mirror system to the previously used system. For example, BOOT files and SYSTEM files of the upgraded mirror system may be synchronized to the previously used system in accordance with the specific synchronizing method in the step 201, the details of which can be found in the step 201, so verbosity is omitted here.
In the method provided by the present embodiment, system files of a currently used system are synchronized to a corresponding mirror system, a system upgrade is performed in the synchronized mirror system, the upgraded mirror system is started after the mirror system is successfully upgraded, and the upgraded mirror system is used as the currently used system, such that the system upgrade does not influence normal use of the currently used system. Meanwhile, the upgrade is performed in the mirror system, which prevents from the case where accidents have occurred in the upgrade of the system that results in that the currently used system can not be normally used, and thus increases safety and stability of the system.
